except such as are enveloped with amber : the 

 larvts of the dragon-fly (Libellula) and of the 

 water-scorpion (Nepa) are, however, said to be 

 found in the Oening limestone, (v. Werner's Ex- 

 tern. Char. p. 142.) Of the second division, i. e. 

 of insects without wings ( Order Apt era, Linn. ) there 

 are several species found petrified, belonging to the 

 genera Cancer, Monoculus ? and Oniscus.-\ 



f. 54. WORMS ( Vermes) are furnished with ten- 

 tacula have no propei\or distinct head, nor legs ; do 

 not undergo any metamorphosis, (v. Syst. Nat. ed. 

 Gmel. p. 3021.) 



Obs. It is from this class that the animal petri- 

 factions, properly so called, principally derive their 

 form. 



The Vermes are divided by Gmelin into five or- 

 ders; ff viz. Intestina, Mollusca, Testacea, 



ether body, as he has not enumerated it among the Entomolithi, in 



his last edition of the sy sterna nature. The fossil Butterjlies,'dud 



and other winged insects, described by some authors, are doubtless 

 nothing more than imperfect vegetable remains as are, also, the 

 supposed delineations of Beetles,&.c. on shale, mentioned by Rich- 

 ardson in a letter to Lhwyd. (v. Lithoph. Brit. Luidii. p. 11 2.)

ff The orders, as they stand in the 12 Ed. of the Syst. Nat. 

 are Intestina, Mollusca, Testacea, Lithophyta, and Zoophyta-~ 

 Gmelin has united the Lithophyta with the Zoophyta ; but has se_ 

 parated, from the liinnean Zooqphyta, all those animalcula which 

 are found in vegetable infusions, &c. forming them, after the 

 manner of Muller, into a distinct order, under the title of lufuso-
